If Luke pushes his sister in a wagon down the driveway that is 14 meters long and it takes 22 Newtons of force, how much work did he do?

Answer 1

Luke does a work of 308Nm

Explanation:

If we have a constant force
`\vec{F}` that acts on a body in the same direction as the displacement
`\vec{s}`, then the work
`W` is defined as the product of the force magnitude
`F` and the displacement magnitude
`s`. In other words:

`W=Fs`, which is valid for a constant force in direction of straight-line displacement.

In this problem:

`F=22N \\ \\ s=14m`

Therefore:

`W=22* 14 \\ \\ \boxed{W=308Nm}`
